Follow one of below steps.
1)
If you want to use [TCP/IP filtering] over the entire adapters, select [Enable TCP/IP Filtering (All
adapters)].
2)
If you don’t want, deselect [Enable TCP/IP Filtering (All adapters)].
7.
Set [TCP Ports], [UDP Ports] and [IP Protocols] for allowed traffic in accordance with the requirements
of ‘TCP/IP filtering’
In case of SAFE-DVR, it only uses ‘
9999
’, ‘
9995
’ and ’
80
’ for [TCP Ports] and [UDP Ports]. So,
add ‘9999’, ‘9995’ and
‘80’ for [TCP Ports] and [UDP Ports], and select [Permit Only]. For [IP Protocols], just select [Permit Only] and
remove all the substances
.
If you do so, the access by ‘Telnet’ or ‘FTP’ is denied. Accordingly, you can set DVR systems more safely against viruses
or hacking.
* Caution
This [TCP/IP filtering] is only for DVR system.
If you use [TCP/IP filtering] on your PC, it cannot access to the internet.
